Basement Project

Looking to install a bathroom in the basement.  After looking at some reference materials and tips looks like there are a few things I’ll need to prepare for.  Before doing any digging it’s best to call Miss Utility http://va811.com/homeowners/what-do-the-markings-mean/

Space Design:
The bathroom area will be 5’x7′ and probably utilized the area under the staircase for storage.  It’s going to be pretty tight but it should work.  Not sure if I want to put in a pocket door or make the door swing out as opposed to swing in. 5x7.large

Check if there is moisture in the walls

Seal the mudsill by applying caulk to preven entry for crawling insects.

Insulation
Seal furnace ducts with duct tape

Exterior Apron insulation is an option.

Insulate foundation walls on the exterior side (and not the interior)
whenever you can. The easiest way to accomplish this is by installing
insulation in the apron area only, so you do not have to excavate all the
way to the bottom of the wall. By adding a layer of horizontal insulation in
the bottom of the trench, you can realize at least 70 percent of the energy
savings of insulating the whole wall,
Because you will be adding width to the foundation wall by installing
exterior insulation, you will need to install flashing to cover the top of the
insulation layer and whatever protective wall surface you cover it with.

Will need to dig out 18″ x 24″ wide trench next to the wall being insulated.
Coat the wall with a layer of bituminous coating to help create another layer of moisture protection for the basement
Line the trench with a 2″ thick layer of course sand, and then strips of rigid foam insulation.  The sand should slope away from the house slightly and the insulation strips should butt up against the foundation wall
Install drop edge flashing to protect the tops of the insulation board and new siding.
Bond strips of rigid foam insulation board to the foundation wall using a panel adhesive that is compatible with foam.
Install siding or faux stone panels.

Rough-ins: Run DWV (drain, waste, and vent) and water and agas supply pipes.  Install electrical boxes and run wiring.
